Amazon Inventory Management That Prevents Stockouts and Storage Fees
Stockouts don't just cost you the sales you missed — they cost you the organic rank you spent months and ad dollars earning, and getting it back is more expensive than never losing it. Overstock costs you the other way, in long-term storage fees, capital tied up in slow SKUs, and a restock limit that shrinks right before Q4. SellaRank manages the line between the two with forecasting built on your actual velocity, seasonality and lead times.
- Never lose rank to an avoidable stockout
- Cut long-term storage and aged-inventory surcharges
- Restock limits protected through peak season
- No obligation
- No long-term contract

What’s included
What's included in our Amazon inventory management services
Restock and reorder planning
Reorder points and quantities calculated against supplier lead times, freight transit and Amazon receiving times, so POs go out before the shortfall, not after.
IPI and capacity management
Ongoing IPI monitoring and the levers that move it — sell-through, stranded inventory, excess and in-stock rate — to keep your storage capacity where you need it.
Stranded and aged inventory recovery
Identifying stranded, unfulfillable and aged stock, then relisting, removing or liquidating it before the surcharges compound.
Shipment and FBA plan management
Shipment creation, box and pallet planning, labelling requirements and tracking through to receipt, plus follow-up on lost or short-received units.
Multi-channel and 3PL coordination
Allocation across FBA, FBM and 3PL, so one channel's demand spike doesn't strand another.

Forecasts that include your ad plan
Most forecasting ignores marketing. If you're about to scale PPC on a SKU, the demand curve changes — we model that.
We treat rank as inventory value
The real cost of a stockout is the organic position you lose. That's factored into every reorder decision.
Fee-aware planning
Size tiers, storage utilisation surcharges, aged inventory and removal costs are all part of the maths.
Month to month
No lock-in.

FAQs
Amazon inventory management FAQs

Ask on WhatsAppHow do I stop running out of stock on Amazon?
By reordering against a forecast that accounts for sales velocity, seasonality, promotions, planned ad spend and total lead time — including supplier production, freight and Amazon's receiving time, which sellers routinely underestimate.
What is an IPI score and why does it matter?
Your Inventory Performance Index is Amazon's rating of how efficiently you use FBA storage, driven by sell-through, stranded inventory, excess inventory and in-stock rate. A low IPI can trigger restock limits and storage overage fees — usually at the worst possible time of year.
How long does it take to recover organic rank after a stockout?
It varies by category and length of the outage, but recovery commonly takes several weeks and often requires paid spend to rebuild velocity. It is materially more expensive than preventing the stockout.
Can you reduce my FBA storage fees?
Yes — through aged inventory removal, better sell-through planning, right-sizing shipment quantities and, where relevant, packaging changes that move a product into a lower size tier.
Do you manage the physical shipments too?
We manage shipment creation, planning, labelling requirements and tracking, and coordinate with your 3PL or freight forwarder.
How much does inventory management cost?
It's included in full account management, or available standalone as a flat monthly retainer quoted after your free audit, so the price reflects the work your account actually needs.
